Drying device for flame-retardant PP plastic processing

The utility model relates to the technical field of PP (polypropylene) plastic processing, in particular to a drying device for flame-retardant PP plastic processing, which comprises a table board, two groups of first transmission cylinders are rotatably mounted on the upper side of the table board, two groups of conveying belts are sleeved on the outer surfaces of the first transmission cylinders in a tensioning manner, and a plurality of fixing shells are fixedly mounted on the outward surfaces of the conveying belts. Two sets of ejection blocks are slidably installed on the upper end face of the fixing shell, a plurality of connecting pieces are slidably installed on the upper end face of the fixing shell and fixedly connected with the ejection blocks, and springs are fixedly installed on the sides, away from the ejection blocks, of the connecting pieces. The material guide rail can enable an operator to install the material on the fixing shell more quickly, time is saved, operation is convenient, and prac
